This is an interesting addition to the history of philosophy generally and an incredible expansion of the history of Idealistic philosophy in particular. The subject is John Scottus Eriugena, a ninth century philosopher and member of The Carolingian intellectual renewal, who, claims Dermot Moran, developed a form of idealism that owed as much, or more, to the Greek neo-platonic tradition as to St. Augustine. Eriugena’s thought anticipated the priority of the subject in the radical way that most scholars believe originated (...) only a thousand years later in German Idealism. Moran, of St. Patrick’s College in Maynooth, Ireland, bases these fascinating claims on an analysis of Eriugena’s most important work, The Periphyseon, or the fourfold division of nature, completed around 867 A.D.
